What cars have the same engine as a Pontiac grand prix 2000?

The 2000 Pontiac Grand Prix came with a few different engine options, so there isn't a single definitive answer. To know which engines are shared, you need to specify *which* engine your Grand Prix has. The most common were:

* 3.1L V6: This engine was shared across many GM vehicles of that era. Finding exact matches is difficult as GM used different internal codes and minor variations across models. You'd likely find this engine in various Buick, Oldsmobile, and Chevrolet models from the same timeframe. However, identifying the exact same engine would require comparing part numbers.

* 3.8L V6 (Series II): Again, this was a common GM engine, and you'd find similar (though not necessarily identical) engines in other GM cars of that period from various brands. The exact internal GM codes would differ, leading to minor variations between applications.

Therefore, I can't give you a definitive list of cars with the *exact same* engine. The best way to find similar engines is to look up the specific engine code (found on your Grand Prix's engine block) and search online databases of automotive specifications.
